JACOB JOHN SCHIMPF, OF TEXARKANA, TEXAS.

TRAM-CAR.

Specification of Letters Patent.

Patented March 24, 1908.

AppIcation filed August 5, 1907. Serial No. 387,038.

T o all whom it may concern.'

Be it known that I, JACOB JOHN Sor-HMPF, a citizenv of the United States, residing at Texarkana, county of Bowie, and State of Texas, have invented certain new and useful Improvements in Tram-Cars, of which the following is a specification.

My invention relates to tram cars and particularly to cars which will support and transport heavy timbers and other objects, and the object is to provide tram cars that are strong and durable and easily moved from place to place with loads of timber and to provide tram cars which are particularly adapted to haul timber into inclosures for treatment with wood preserving fluids. For this purpose tram cars are needed which will occupy a small space and yet carry a large proportion of timber to the size of the car.

Other objects and advantages will be fully explained in the following description and the invention will be more particularly pointed out in the claims.

Reference is had to the accompanying drawings which form a part of this application and speciiication.

Figure 1 is a side elevation of the tram car. F ig. 2 is a plan view of the same. Fig. 3 is an end elevation. Fig. 4 is a horizontal section of a Wheel and a journal for the axle of the tram way. Fig. 5 is a vertical section of a journal for the axle, illustrating the manner of placing the roller bearings.

Similar characters of reference are used to indicate the same parts throughout the several views.

The tram car has 4two longitudinal beams or rails 1 and 2 which constitute supports Jfor the timber bearing arms 3 and 4. Wheels 5 are provided with axles 6. Bearings 7 are provided for connecting the axles 6 to the beams 1 and 2. The wheels 5 are made rigid with the axles by set screws or bolts 8. The bearings or journals 7 are provided with roller bearings 9. The journals have apertures 10 through which the journals may be oiled either when the cars are loaded or unloaded. The beams 1 and 2 are provided with horizontal braces 1 1 which are bolted together and bolted to the flanges ofthe beams 1 and 2. The timber bearing arms 3 and 4 are clamped on the beams 1 and 2 by braces 12 and 13. The bearing arms 3 and 4 are horizontally disposed relative to the rails or beams 1 and 2 and are curved upwards at the sides of the car. The braces 12 and 13 are placed on top of the beams 1 and 2 and bent down between the rails and bolted to the horizontal portion of the bearing arms 3 and 4 between the rails. The braces are then extended horizontally to the curved portion of the bearing arms and then bent with the curve of said bearing arms and bolted thereto at the points 14 and 15 where there is the greatest strain on the arms. `The bearing or carrying arms are thus braced at the points where bracing is most needed and are held rigidly .and securely to the rails or main supporting beams by the braces. The load is thus suspended on the rails and the weight is thrown on the roller bearings of the axles. The braces 12 and 13 will hold the carrying arms against outward spreading.

Having fully described my invention, what I claim as new and desire to secure by Letters Patent, is-

1. A tram car having a pair of longitudinal beams, journals provided with roller bearings bolted to said beams, axles engaged by said journal bearings and wheels rigid with said axles, carrying arms extending under said beams and curved upwards at the sides of said car, and braces for said carrying arms placed above said beams and bolted to said carrying arms and clamping said carrying arms to said beams.

2. A tram oar having a pair of longitudinal supporting beams, roller bearings secured to said beams, axles journaled in said bearings and having wheels rigid with the axles, transverse carrying arms extending under said beams and curved upwards at the outer ends, and transverse bars clamping said carrying arms to said beams and bracing said carrying arms against outward strain.

3. A tram carhaving a pair of longitudinal supporting beams, axle bearings attached to said beams, axles j ournaled in said bearings and provided with wheels rigid with sald axles, braces for said beams holding the same at a xed distance apart, transverse carrying presence of two Witnesses, this 22d day of arms extending under said beams and curved July7 1907. upwards at the outer ends thereof, and transverse hars clamping said carrying arms to JACOB JOHN SCHIMPF' 5 said beams and bracing said carrying arms Vtnesses:

against outward strain. GEORGE WILLIAM WALKER,
